Are my images uploaded to a server?

No. Compression happens entirely in your browser, so your images never leave your device. That makes it private and fast, with no waiting on an upload.

Which image formats can I compress?

JPG, PNG, and WebP. You can also convert between formats with the related image converter tool.

Will compressing reduce the quality?

You control the quality. In most cases you can cut the file size by half or more with no visible difference, which is called visually lossless compression.

Is this image compressor free?

Yes. It is completely free, needs no signup, and runs in your browser with nothing uploaded.

Why should I compress images before putting them on a website?

Images are usually the heaviest part of a web page, and heavy pages load slowly. Slow pages lose visitors and sales, so smaller images mean a faster site and better results.

How to compress an image

Drag in a JPG, PNG, or WebP, choose the quality you want, and download the smaller file. It takes a couple of seconds and runs entirely in your browser, so nothing is uploaded and your original stays on your device.

Why compress your images

Images are usually the heaviest thing on a web page, and heavy pages load slowly. A page that loads in about one second holds far more visitors than one that takes five, and every extra second costs you conversions. Compressing also helps you beat email attachment limits, save storage, and upload faster to marketplaces and social platforms.

Private by design

Many online compressors upload your photos to their servers. This one does not. Everything happens locally in your browser, so your images never leave your device. That matters for personal photos, client work, and anything confidential.

Common uses

Website and blog images, including WordPress uploads.
Email attachments that are too large to send.
Product photos for marketplace and social listings.
Shrinking a scanned image before you drop it into a PDF.
